As a transgender livibg in California myself it's cool that this is a thing now but at the same time if it wasn't a thing it wouldn't affect me much, I mean this seems more like a thing for dressing/locker rooms or shower rooms, I mean in a bathroom each toilet is walled off from each other so no one sees anything but in a locker room or shower room i think it makes more sense I mean think about it, you're a woman in a mans body or a man in a woman's body and you're in a room with everyone of you're opposite sex (mentally not physically) who are undressing themselves, it easy to see why a transgender person would be uncomfortable
